John, 30, was spotted in WHITE nightclub on Saturday night trying it on with mystery babes.

In images obtained by Daily Star Online, Vicky's fella – who sources say was acting like he was "on the prowl" – can be seen with his hands around a random brunette's waist as she rests her hands against his chest.

Another shot sees the Newcastle businessman lean in towards the mystery woman's face.

A source at the club told Daily Star Online: "John just seemed like a total sleaze.

"He had hired a table out with his friend and was just walking around with a large bottle of vodka in his hand try to beckon people over.

"I don’t think many people knew who he was as nobody seemed impressed."

But that's not all, the onlooker explained how John was also initially making a move on another lady, wearing a white dress.

The source added: "The music was pretty loud so I couldn’t really hear too much but from the bits and bobs I could hear, there was no mention of Vicky."

The insider added: "I think it’s safe to say he has a wandering eye.

"The woman in white was having none of it but he seemed incredibly flirty with the woman in the black dress.

"He kept trying to lean in.

"Once they turned him down, he would just move onto the next one."

The revelations will come as a major blow to Vicky who has been engaged to John since July 2017.

Insisting that they think the Geordie Shore star has cause for concern, the partygoer added: "He definitely seemed like he was on the pull while Vicky is putting up stuff on social media to do with wedding planning.

"There was a few others he tried it on with too but again he had no luck.

"He ended up just leaving the club with his mate an hour or so after midnight.

"I just feel bad for Vicky. This all happened a week before her birthday."

Last month, the couple embarked on a "make or break" trip to Dubai after Vicky confessed they were "fighting a battle to make [their relationship] work".

However, just a few days ago, Vicky posted a snap on Instagram of her wearing a wedding dress along with the caption: "I can’t wait to try on wedding dresses again soon."
